The subject disclosure describes a structure and method that generates the average of two or more reference quantities (e.g., reference voltage potentials) and monitors the integrity of the voltage reference potentials. The subject technology produces a reference with improved accuracy and more accurate monitoring compared to traditional techniques. For example, the subject technology provides for a fault circuit that includes a monitoring circuit, and an averaging circuit configured to receive a plurality of reference signals and to produce an averaged reference signal based on the received plurality of reference signals. In some examples, the monitoring circuit is configured to receive the averaged reference signal from the averaging circuit, compare the averaged reference signal to each of the plurality of reference signals, and generate a fault signal when the averaged reference signal deviates from at least one of the plurality of reference signals by at least a threshold value.
